L Dike

A stream near Flinton, East Riding of Yorkshire. No gauge of its own: what the river map and the banked data say about it.

L Dike is a stream on Ordnance Survey’s river map near Flinton, East Riding of Yorkshire, with about 5.2 km of mapped channel. On the map it flows into Lambwath Stream, which flows on into Foredyke Stream, then Holderness Drain; beyond that the map has a gap, so where it goes next is not known.

Next gauge downstream

Bransholme Great Culvert Pumping Station on Holderness Drain, about 14 km along the river below where L Dike ends on the map.

After that, East Hull Hedon Road, about 22 km along the river.

No gauge measures L Dike itself. A gauge downstream shows water that has already passed it, mixed with everything else that has joined on the way, so it says nothing exact about this stream.

Water-sampling points on L Dike

1 Environment Agency sampling point is placed on this stream. These are dated samples taken by hand, not live readings, and FloodRadar does not grade them.

A sample is taken on a date; it says nothing about the water today. A sample below an overflow does not by itself show where anything in it came from.

What this page can and cannot tell you

Its line, its name and where it flows come from Ordnance Survey’s river map (OS Open Rivers, edition 2026-04), which leaves out many small streams, ditches and culverts. “Flows into” is the map’s word: a channel that is not on the map is not shown here, which does not mean it is not there.
No gauge measures L Dike itself, so its own level is not known here.
No storm overflow is placed on this stream on the river map. That is not the same as none: the map cannot place every overflow.
Water samples are England’s only (the Environment Agency’s archive), placed where the map can place their sampling point.
Nothing on this page says whether any place floods. For an address, see its postcode page.
